Detailed Description
The invention will be further described with reference to the following examples.
The utility model discloses a concrete implementation mode of material structure of taking off of cutting off mould punches a hole, as shown in fig. 1 to 2, it is mainly installed in the lower mould of mould.
In this embodiment, the upper die is fixedly connected with an upper die base 1, an upper clamping plate 2, a stop plate 3 and an upper stripper plate 4 from top to bottom in sequence, and the punch is fixedly installed in the upper die. The lower die comprises a lower die plate 5, a lower cushion plate 6 and a lower die base 7 which are fixedly connected from top to bottom in sequence, and the stripping structure comprises an equal-height bolt 82, an equal-height sleeve 83, a spring 84 and a floating insert 81. The lower template 5 is provided with a first through hole for accommodating the floating insert 81, the lower backing plate 6 is provided with a second through hole for mounting the equal-height sleeve 83, the lower die base 7 is provided with a third through hole for passing the equal-height bolt 82, and the equal-height sleeve 83 is fixedly mounted in the second through hole and can be fixed in an interference fit mode. In an assembly state, the equal-height bolt 82 is inserted into the third through hole and sequentially penetrates through the equal-height sleeve 83 and the first through hole, the head of the equal-height bolt 82 abuts against the equal-height sleeve 83, and the thread part of the equal-height bolt 82 is fixedly connected with the floating insert 81; one end of the spring 84 is fixedly connected with the floating insert 81, and the other end of the spring 84 abuts against the equal-height bolt 82. In addition, the floating insert 81 can also be cut out by a common template with the lower template 5, so that the material is greatly saved.
In this embodiment, the length of the equal-height sleeve 83 is greater than the thickness of the lower cushion plate 6, so that the lower cushion plate 6 is prevented from being worn due to the fact that the floating insert 81 directly impacts the lower cushion plate 6, and if the equal-height sleeve 83 is damaged, the equal-height sleeve 83 can be replaced, and maintenance cost is reduced.
